Do what you have always done and you will always be what you have always been

Your attitude is everything. Pick a good one.

Your limitation - its only your imagination.

You can be shown the path, but only you can make the first step.

I can is 100 times more important than IQ.

There are no bad mistakes in maths, only discoveries.

The journey of a thousand miles begins with one step. 

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

It is never too late to become what you might have been

Everything that happens was once a dream.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Tomorrow is worth more than yesterday but less than today.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

I think, therefore I am.
